Yang Wei Mai (Yang Wei)
阳维脉 · Yang Wei Mai
Overview
The Yang Wei Mai is one of two 'linking vessels' (Wei Mai) that serve to coordinate the body's meridian network. While the primary meridians each have their individual functions, the Yang Wei Mai ensures that the six Yang meridians work together as a coherent system. Its clinical importance lies primarily in its management of the exterior defense and its role in conditions where the body's Yang defenses have been compromised.
The confluent point pair of TB-5 (Wai Guan) and GB-41 (Zu Lin Qi) opens both the Yang Wei Mai and the Dai Mai, creating a combination that addresses the lateral body comprehensively. This pairing is used for conditions affecting the sides of the head (temporal migraine), the lateral torso (rib pain), and the lateral legs (hip and outer thigh conditions), as well as for gynecological conditions involving the Dai Mai.
In the Shang Han Lun tradition, many of the patterns involving alternating chills and fever, bitter taste, and lateral symptoms are understood through the Yang Wei Mai framework. The classic Xiao Chai Hu Tang (Minor Bupleurum Decoction) treats precisely this pattern -- a pathogen caught at the Shaoyang pivot that the Yang Wei Mai governs.
Pathway
The Yang Wei Mai originates at BL-63 (Jin Men, Metal Gate) on the lateral foot, ascends the lateral malleolus and leg via Gallbladder meridian points, crosses the hip region, ascends the lateral torso through the Gallbladder and Triple Burner meridian pathways, reaches the shoulder, crosses the forehead, and terminates at GV-16 (Feng Fu, Wind Mansion) and GV-15 (Ya Men, Mute's Gate) at the base of the skull. It connects the exterior Yang meridians along the body's lateral and posterior aspects.
Functions
The Yang Wei Mai serves as a 'linking vessel' that connects all the Yang meridians, ensuring coordination and communication between them. It governs the body's exterior defense by regulating Wei Qi across the Yang meridian network and manages the body's response to external pathogenic invasion. When the Yang Wei Mai is compromised, the Yang meridians lose coordination, and the defensive barrier weakens, leading to recurrent chills and fever.
Related Organ
The Yang Wei Mai connects primarily with the Gallbladder, Triple Burner, Small Intestine, and Bladder meridians -- the body's Yang channels. It has a particular relationship with the Gallbladder (Shaoyang) as a pivot between exterior and interior defense.
Related Emotion
The Yang Wei Mai relates to the sense of being defended and secure in the external world. When compromised, there is a vulnerability and exposure -- a feeling that one's defenses are down and that threats from the environment cannot be adequately managed.
Common Symptoms of Imbalance
Alternating chills and fever (the cardinal Yang Wei Mai symptom), recurrent external pathogen invasion, temporal headache, lateral body pain, difficulty coordinating movement, a feeling of the body's defenses being down, susceptibility to wind and cold, pain that moves along the lateral body
Key Acupressure Points
TB-5 (Wai Guan / Outer Pass) -- confluent point that opens the Yang Wei Mai. Paired with GB-41 (Zu Lin Qi) for treating Yang Wei Mai disorders. Treats alternating chills and fever, temporal headache, lateral rib pain, and ear conditions. GV-16 (Feng Fu / Wind Mansion) -- terminal point, treats Wind invasion, headache, and neck stiffness. GB-20 (Feng Chi / Wind Pool) -- treats the common cold, headache, and defends against Wind at the Yang Wei Mai's occiput region.
Balancing Practices
TB-5 (Wai Guan) acupressure at the first sign of cold or flu to strengthen the exterior defense. Lateral body stretches. Wind-protective practices during windy weather (wearing a scarf over the neck, avoiding drafts). Qigong practices that strengthen Wei Qi. Building resilience through graduated cold exposure. Avoiding overwork and sleep deprivation that weaken the Yang Wei Mai's defensive function.
